Upgrade from 7.2.1 to 7.3 - database error

I've upgraded from 7.2.1 to 7.3 with all steps. 
automatic steps and manual steps.
No errors on the screen (see the images below).

But know I can't call my site www.senolive.eu anymore.

The error message is "Database query error"

What can I do know to become my website? 

tiff file format can not be displayed in a browser.

We need the full error report; either sent to the site's admin email or in your error logs.

No need to include the back trace.

I also ran into a "database error" during my upgrade, I will share my problem/resolution & hopefully it helps..

I have a dedicated server, so most of the time I SFTP using my root Acct.  At times the old files don't get replaced as expected when I use the site Acct to transfer files using Filezilla.  However, since I use root Acct, all the files I transfer using root Acct will have OWNER as root. This time I forgot to change the OWNER back to the site user, and as result I got the "database error".

> And here is what I did to fix it:
chown -R siteuser:siteuser /home/siteuser/public_html/* 

Also, make sure to remove the .hsaccess from folder /upgrade before you perform your upgrade 

> Lastly, if you have ssh access to your site, follow these steps:
1. SFTP the full upgrade file to your site host  (don't extract it yet)
2. Using Putty, access the patch file you just uploaded and extract it in a /tmp folder
3. cp -rf /tmp/patch730/*  /home/siteuser/public_html/

This method will make sure all the old files get replaced accordingly. I had some issues with Filezilla not replacing my old files when I login as a regular user, but Filezilla appears to work fine when I use root Acct to transfer files. So, steps above may work for your if you don't have root access to your site.

Good luck ! 

I can see your site in my browser, Michelle; although it's all a mystery.

Don't use Filezilla, it is a buggy FTP client.

 You can use wget to just transfer the zip file from Boonex to your server.

 Why not just use the user and owner of the web files?

hi. thanks for your answers. 

With the wonderfull support the problem was resolved. 

There was a problem with installation of the wall module (timeline). 

In the administration console I removed this module an reinstall it then. 

Now all is correct. This is why you can see the site TravelNotes. 

:)

very good help here.
